Too many to list here, but the popularity of HVDC systems is increasing. There is a wikipedia article on the subject. [But it suggests the New Zealand system is to be dismantled, whereas it is to be replaced in a year with an upgraded system of greater power.]
the one of the best station in kolar.. karnataka state...
it will be implemented soon...planning is in progress

The corona effect is less pronounced in High Voltage Direct Current (HVDC) lines primarily due to their design features and operating characteristics. HVDC systems typically operate at higher voltages and lower frequencies compared to AC systems, resulting in lower electric field gradients around the conductors. Additionally, HVDC lines often utilize larger conductor diameters and specific geometries that help reduce surface irregularities, minimizing the likelihood of corona discharge. As a result, HVDC lines experience reduced energy losses and improved efficiency in transmission over long distances.
HVDC Moyle was created in 2001.
The HVDC light is a power system that is designed to transmit power underground and under water. The HVDC light also has numerous environmental benefits, including invisible power lines, neutral electromagnetic fields, and oil free cables.
We can use DC too for the transmission system. Refer HVDC transmission system.
'HVDC' stands for high-voltage, direct current.
